You can find the full details of Medicare Part D Prescription Coverage or Creditable Coverage on page 15 of: http://www.va.gov/healthbenefits/resources/publications/IB10-185-health_care_benefits_overview_2012_eng.pdf. If you qualify for Medicare Part D prescription drug coverage, enrollment in the VA health care system is considered creditable coverage for Medicare Part D purposes. This means that VA prescription drug coverage is at least as good as the Medicare Part D coverage. Since only Veterans may enroll in the VA health care system, dependents and family members do not receive credible coverage under the Veterans enrollment. However, there is one significant area in which VA health care is NOT creditable coverage: Medicare Part B (outpatient health care, including doctors fees). Creditable coverage for Medicare Part B can only be provided through an employer. So although a Veteran may avoid the late enrollment penalty for Medicare Part D by citing VA health care enrollment, that enrollment would not help the Veteran avoid the late enrollment penalty for Part B. VA does not recommend Veterans cancel or decline coverage in Medicare (or other health care or insurance programs) solely because they are enrolled in VA health care. Unlike Medicare, which offers the same benefits for all enrollees, VA assigns enrollees to enrollment priority groups, based on a variety of eligibility factors, such as service-connection and income. There is no guarantee that Congress will allocate enough funding for VA medical care to support all enrollment priority groups. This could leave Veterans, especially those enrolled in one of the lower-priority groups, with no access to VA health care coverage. Due to this, it may be in the best interests of the Veteran to have another health coverage. In addition, a Veteran may want to consider the flexibility afforded by enrolling in both VA and Medicare. For example, Veterans enrolled in both programs would have access to non-VA physicians (under Medicare Part A or Part B) or may obtain prescription drugs not on the VA formulary if prescribed by non-VA physicians and filled at their local retail pharmacies (under Medicare Part D).
